3/// A simple error type that wraps a string message.
4///
5/// Use this when you need a quick error without defining a custom error type.
6/// Works with [`ErrorReport`](crate::ErrorReport) and [`ResultExt`](crate::ResultExt).
7///
8/// # Example
9///
10/// ```rust
11/// use charon_error::StringError;
12///
13/// let err = StringError::new("something went wrong");
14/// assert_eq!(err.message, "something went wrong");
15/// ```
